Definitions

  • the present invention relates to a particular 17 ⁇ -anilide-4-aza-5 ⁇ -androst-1- en-3-one derivative, as a surprisingly potent and selective dual inhibitor of type 1 and 2 human 5 ⁇ -reductase.
  • Androgens are responsible for many physiological functions in both males and females. Androgen action is mediated by specific intracellular hormone receptors expressed in androgen responsive cells. Testosterone, the major circulating androgen, is secreted by Leydig cells of the testes under the stimulation of pituitary-derived luteinizing hormone (LH). However, reduction of the 4, 5 double bond of testosterone to dihydrotestosterone (DHT) is required in some target tissues, such as prostate and skin, for androgen action. Steroid 5 ⁇ -reductases in target tissues catalyze conversion of testosterone to DHT in an NADPH dependent fashion as shown in Scheme A.
  • DHT dihydrotestosterone
  • isozyme specific and dual inhibitors of the two isozymes of 5 ⁇ -reductase will depend upon the type of disease treated (benign prostatic hyperplasia, prostate cancer, acne, male pattern baldness or hirsutism) as well as the stage of the disease (prevention versus treatment) and the anticipated side-effects in the intended patients (for example treatment of acne vulgaris in pubescent males).
  • H 5 ⁇ -reductase inhibitors have been the subject of active research worldwide. For example, see: Hsia, S. and Voight, W., J. Invest. Derm., 62, 224 (1973); Robaire, B. et al., J. Steroid Biochem., 8, 307 (1977); Petrow, V. et al., Steroids, 38, 121 (1981); Liang, T. et al., J. Steroid Biochem., 19, 385 (1983); Holt, D. et al., J. Med. Chem., 33, 937 (1990); U.S. Patent No.
  • One aspect of the present invention is the compound of formula (I),
  • a method of inhibiting testosterone-5 ⁇ -reductases comprising contacting testosterone-5 ⁇ -reductases with the compound of formula (I). 2. A method of treatment of androgen responsive or mediated disease comprising administering an effective amount of the compound of formula (I) to a patient in need of such treatment.
  • a method of treatment of androgen responsive or mediated disease comprising administering an effective amount of the compound of formula (I) to a patient in need of such treatment in combination with an antiandrogen such as flutamide.
  • a method of treatment of benign prostatic hyperplasia comprising administering an effective amount of the compound of formula (I) to a patient in need of such treatment in combination with an alpha 1 adrenergic receptor blocker ⁇ e.g. terazosin).
  • an alpha 1 adrenergic receptor blocker ⁇ e.g. terazosin
  • a method of treatment of benign prostatic hyperplasia comprising administering an effective amount of the compound of formula (I) to a patient in need of such treatment in combination with an anti-estrogen.
  • the compound of the present invention may be prepared by the methods taught in US Patents 4,377,584 (hereinafter, , "584") and 4,760,071 (hereinafter, "O71") both incorporated herein by reference.
  • the compound of formula (I) may be prepared by the procedure shown in Scheme I and II.
  • Enzyme activities are measured using microsomes derived from human adrenal tissues. Microsomes were prepared by homogenization of the tissue followed by differential centrifugation of the homogenate. Microsome extracts were incubated with varying concentrations of dehydroepiandrosterone (DHEA), 1 mM NAD+- and varying amounts of the compound of Formula (I), i.e. a test compound, in pH 7.5 buffer for a period of time within the range of 1 to 60 minutes. Corresponding incubations were carried out with no test compound as a control study. The percentage of conversion of DHEA to androstenedione in the presence of test compounds compared to the corresponding conversion in the control study was estimated using HPLC with radiochemical detection. The results of these assays appear as Kj's reported in Table 1.
  • the steroid 5 ⁇ -reductase inhibitor of the present invention is useful in the treatment of androgen responsive diseases , e.g., benign and malignant diseases of the prostate, especially benign prostatic hyperplasia, in a manner similar to that for other 5 ⁇ -reductase inhibitors such as finasteride and SKF105657.
  • the compound of the present invention has a surprisingly long half-life and potency compared to finasteride and SKF105657.
  • the formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing the active compound into association with a carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing the active compound into association with a liquid carrier or a finely divided solid carrier and then, if necessary, shaping the product into desired unit dosage form.
  • a tablet may be made by compression or molding, optionally with one or more accessory ingredients.
  • Compressed tablets may be prepared by compressing in a suitable machine the active compound in a free-flowing form, e.g., a powder or granules, optionally mixed with accessory ingredients, e.g., binders, lubricants, inert diluents, surface active or dispersing agents.
  • Molded tablets may be made by molding in a suitable machine, a mixture of the powdered active compound with any suitable carrier.
  • reaction mixture is filtered through a bed of celite (50 g) and the solid is washed with water and the filtrate concentrated in vacuo to remove f-butanol (ca. 175 ml).
  • the resultant aqueous solution is acidified to pH 2 with 36% HCI and the extracted 4 times with chloroform.
  • the chloroform layers are combined and washed with water, brine, dried over sodium sulfate, filtered and concentrated in vacuo to give 17 ⁇ -N-(2,5-bis(trifluoromethyl))phenylcarbamoyl-5-oxo-A-nor-3,5-secoandros- tan-3-oic acid as a off-white solid; yield: 20.5 g (100% crude). This material is carried directly into step C below.
  • the silicone fluid and active compound are mixed together and the colloidal silicone dioxide is added to increase viscosity.
  • the material is then dosed into a subsequently heat sealed polymeric laminate comprised of the following: polyester release liner, skin contact adhesive composed of silicone or acrylic polymers, a control membrane which is a polyolefin ⁇ e.g. polyethylene, polyvinyl acetate or polyurethane), and an impermeable backing membrane made of a polyester multilaminate.
  • the resulting laminated sheet is then cut into 10 sq. cm patches.
  • the active compound and the starch are granulated with water and dried. Magnesium stearate is added to the dried granules and the mixture is thoroughly blended. The blended mixture is compressed into tablets.
